Specification of Letters Patent.

Application filed January 3, 1918, Serial No. 210,131. Renewed September4, 1919. Serial No. 321,656.

To all whom t may concern s Be it known that I, CHARLES J. SCHIEMER, acitizen of the United States of America, and a resident of Mount Joy,county of Lancaster, and State of Pennsylvania, have invented certainnew and useful Iniproveprovided with a suitable clamp at its lower.

end to enable the standard to be attached to a suitable support. At theupper end of the standard is cast integral a ,stationary upright jawwhose nut-engaging surface faces laterally with respect to the standardyand is provided with serrations. Formed integral with the jaw Z) andprojecting rearwardly from its side edges is a pair of cheekplates c, inthe upper ends of which are journaled the ends of a horizontal shaft CZ.Attached to this shaft el is an eccentric c which is attached to ahand-lever f, whereby the eccentrical cani will be supported by theshaft CZ and the eccentric may be rocked in the bearings in thecheek-plates.

Embracing the periphery of the cam or eccentric is the rear end of ayoke g consisting of a steel rod bent upon itself, the two free ends ofthe yoke thus formed being slidingly mounted in tubular supportingguides L formed integral with the stationary jaw -b at one edge thereof.The free ends of the yoke-arms extend beyond the tubular guides It andcarry the movable jaw z' arranged in upright position and projectinglaterally from theyoke-armsso as to be positioned at a point oppositethe stationary jaw and thus coperate with the stationary jaw when theyoke-arms are drawn rearwardly. This movable jaw is attached to theyoke-arms by means of a pair of tubes y' formed-integral with the jawVand through which the yoke-arms pass, these tubular members beingsuiiiciently long to give the jaw a broad and substantial bearing orsupport upon the yoke-arms. The z' is adjustably mounted on theyoke-arms so as to enable it to be positioned nearer to or farther fromthe stationary jaw to adapt the device for different sized nuts. As ameans of providing for this adj ustability of the movable jaw, I provideeach yoke-arm with a series of notches 7c, these notches beingpositioned so as to be engaged by the opposite edges of the plate Zpivotally connected to the front face of the jawn' by pivot-screw m. Itwill be observed that by swinging plate Z upwardly by means of itshandle n, the edges of the plate will be removed from the notches k,whereupon the movable jaw may be slid along the free ends of theyokearms and again locked in place by swinging the plate downwardly.

As stated, the eccentric e lies within the bent end of the yoke, thiseccentric being so positioned that when the lever f is swung downwardlythe eccentric bears` against the connecting bar of the yoke and drawsthe yoke rearwardly, thereby drawing the movable jaw toward thestationary jaw. When the lever f is raised, the yoke and the movable jawwill be pushed forwardly by means of plate.0,who'se bent ends p engagerespectively one side of the eccentric and the rear side of the yoke,this plate being slotted at Q for the passage of the shaft d. This plate0 may be affixed to the yoke in any suitable manner, preferably byraising one of the bent parts p to the -connecting bar of the yoke. Itwill be observed that when the leverV is raised, the eccentric willpress against the adjacent lip p of the plate 0 and thus, through themedium of the other bent end p, push the yoke forward.

The nature and scope of the invention having been thus indicated and itspreferred embodiment having been specifically described, what is-claimed as new is:

1. In a nut cracker, a support carrying a stationary jaw, a slidableyoke mounted in said aw and carrying a companion aw, an eccentricjournaled in the rear of the stationary aw and provided with anoperating handle, anda plate connecting the yoke to the forward face ofthe eccentric.

2. The strgucture recited in claim l, said plate being slotted for thepassage of the eccentric shaft and having bent ends engagingrespectively one side of the eccentric and the rear end of the yoke.

3. In a nut cracker, a Support carrying a stationary jaw, a yokeslidably mounted in said jaw and embodying a pair of parallel arms,means for slidingsaid yoke back and forth, a movable jaw adj ustablymounted on the bars of the yoke, the means of adjustment consisting innotching the yoke arms and providing a pivoted plate on the movabilejavv for engaging in said notches.

4. A nut cracker consisting of a support Copies of this patent may beobtained for provided with a stationary jaw, an eccentric and leverjonrnaled on said stationary jaw, a one-piece rod bent to form a yokehaving a pair of parallel arms Working in tubular bea-rings carried bySaid stationary jaw, the

bent ends of the yoke being arranged to be CHARLES J. SCHIEMER.
